Acoustic Pattern Recognition and Courtship Songs: Insights from Insects.

Across the animal kingdom, social interactions rely on sound production and perception. From simple cricket chirps to more elaborate bird songs, animals go to great lengths to communicate information critical for reproduction and survival via acoustic signals. Insects produce a wide array of songs to attract a mate, and the intended receivers must differentiate these calls from competing sounds, analyze the quality of the sender from spectrotemporal signal properties, and then determine how to react. Insects use numerically simple nervous systems to analyze and respond to courtship songs, making them ideal model systems for uncovering the neural mechanisms underlying acoustic pattern recognition. We highlight here how the combination of behavioral studies and neural recordings in three groups of insects-crickets, grasshoppers, and fruit flies-reveals common strategies for extracting ethologically relevant information from acoustic patterns and how these findings might translate to other systems.

Ecological factors drive the divergence of morphological, colour and behavioural traits in cactus wrens (Aves, Troglodytidae).

The study of ecological mechanisms influencing organisms' phenotypic variation is a central subject of evolutionary biology. In this study, we characterized morphological, plumage colour and acoustic variation in cactus wrens Campylorhynchus brunneicapillus throughout its distribution. We assessed whether Gloger's, Allen's and Bergmann's ecogeographical rules, and the acoustic adaptation hypothesis relate to geographical trait variation. We analysed specimen coloration in belly and crown plumage, beak shape and structural song characteristics. We tested whether the subspecific classification or the peninsular/mainland groups mirrored the geographical variation in phenotypes and whether ecological factors were associated with patterns of trait variation. Our results suggest that colour, beak shape and acoustic traits varied across the range, in agreement with two lineages described by genetics. The simple versions of Gloger's and Allen's rules are related to variations in colour traits and morphology. Conversely, patterns of phenotypic variation did not support Bergmann's rule. The acoustic adaptation hypothesis supported song divergence for frequency-related traits. Phenotypic variation supports the hypothesis of two taxa: C. affinis in the Baja California peninsula and C. brunneicapillus in the mainland. The ecological factors are associated with phenotypic trait adaptations, suggesting that divergence between lineages could result from ecological divergence.

A Digital Music-Based Mindfulness Intervention ("healing attempt") for Race-Based Anxiety in Black Americans.

This study replicates and extends findings that "healing attempt"-a brief digital music-based mindfulness intervention-represents a feasible and potentially effective intervention for race-based anxiety in the Black community.

Family-Integrated Neonatal Music Therapy: A Descriptive Pilot Study of Parental Perceptions on Music Therapy Participation and Long-Term Influences.

Purpose: Following a family-integrated music therapy (MT) approach, describe parental perceptions on the use of music with maternal voice to soothe and connect with the infant and the long-term influence of this approach on parents' integration of music postdischarge. Design: In this descriptive, observational within-subjects pilot cohort study, board-certified music therapists instructed and recorded mothers in singing selected songs of kin. Infants received the recorded sessions weekly from enrollment to discharge. Parents were surveyed at 1- and 6-year postdischarge. Sample: Medically stable preterm infants (n = 12) and their English-speaking parents (n = 17). Main Outcome Variable: Parent perceptions on participation and long-term influence on family integration of music during hospitalization and postdischarge. Results: Parents reported knowledge of soothing and interacting with their children as the highest benefit of MT. They also perceived the effects of an easier transition home, enhanced learning and child development, and personal benefits of positive mood and enhanced relaxation.

Tamil Songs of Mourning: Understanding the Reflection of Times in Oppari Songs.

Oppari-the folksong of Tamil Nadu and North-Eastern parts of Sri Lanka, is known as the Tamil song of mourning. The practice of women singing oppari is prevalent in the suburban and rural spaces of Tamil Nadu. They form a circle, weep, beat their chest, wail and jump on the beats of Parai (single-sided drum) music on the death of a member of a family as reported by Srinivas (Oppari: An art of Weeping, Wailing and Lamenting, 2019). The women in the region express their grief over the death of their beloved with the lyrics of oppari songs. Of late, professional oppari singers, including both female and male, have been invited to rural and urban Tamil Nadu on the death of a member in the well-off families to mourn for the deceased person. This distinctively South Indian genre of weeping songs has evolved with time. The lyrics of the oppari songs have been blended with the essence of the periodical changes. The content, context, and presentation of the oppari songs have been playing important roles to reflect the makeovers of times. This study attempts to understand the reflection of times in the lyrics of oppari songs by assiduously employing semiotic analysis. The analysis of the words of the content, context indicated and presentation of subject, period, and expression in lyrics of the oppari songs has been made in the paper. The analysis of three oppari songs gives some significant ideas about the different times of history.

Songs for health education and promotion: a systematic review with recommendations.

OBJECTIVE: We aimed to assess evidence of the effectiveness of song-based public health programmes and to examine the analyses of song lyrics to learn what their key qualities for public health promotion are. METHODS: A systematic search was employed to identify empirical studies that examined song interventions for public health education and promotion. We searched the following databases: MEDLINE, PubMed, CINAHL, PsycINFO and AMED. We also backwards searched references of all relevant studies. RESULTS: Of the 137 studies identified, ten studies were included: four were quantitative and six were qualitative. The qualities of the included studies were assessed to be fair or good. The studies were from developing/low-income countries, South Africa and the United States, involving children and adults. Through a narrative data synthesis, three themes were identified; song-based programmes increased public health knowledge and changed behaviours. Additionally, developing songs for public health promotion involved consultations with local people utilising culturally and socially relevant genres or songs. CONCLUSION: Although the current evidence is limited by the small number of available studies and their heterogeneity, there is evidence that songs may be an effective method to deliver public health messages that result in improved education and changes in behaviour. Several advantages of using songs as public health strategies were identified that included their social and cultural relevance, ubiquity, low cost and enjoyment. Given these advantages, further research with the robust methodology is required to assess the benefits of songs using quantifiable outcomes along with evaluation of processes. We recommend that public health professionals, stakeholders and communities utilise songs as public health strategies.

"We Need a Song of Hope": Responding to the COVID-19 Informational and Psychospiritual Needs of Residents of a Gated Community in the Philippines.

The brutal disruptions caused by the novel coronavirus (COVID-19) pandemic require dynamic ways of responding, not only to the informational needs of communities, but also engaging and creating interventions they consider relevant to their psychospiritual needs. Using the design thinking steps, we identified, developed and tested the type and nature of a unique song which residents of a gated community needed in their journey through COVID-19 lockdowns and government restrictions. The design thinking model provided clear steps for engaging residents to develop an anti-COVID-19 song of hope to cope with the physical, sociopolitical, psychological and spiritual trauma caused by the pandemic.

Artistic representations of infectious disease.

Artistic representations of disease are widespread yet largely ignored in health psychology research. In this paper we use two infectious diseases, tuberculosis and the plague, as tracers to study how infectious diseases are represented in novels, films, paintings, and songs. They were represented especially in terms of their causes and seriousness. Studying how diseases are represented in various art forms extends our understanding of how they are socially constructed. This knowledge can also be incorporated into the training of health care providers to sensitize them to issues in patient care.

Using participatory risk analysis to develop a song about malaria for young children in Limpopo Province, South Africa.

BACKGROUND: In 2015, malaria infected over 212 million people and killed over 429,000 individuals, mostly children under 5 years of age, with 90% of malaria cases occurring in sub-Saharan Africa. The aim was to develop an age and culturally appropriate song for Tshivenda-speaking children under 5 years of age to decrease the risk of malaria in Limpopo Province, South Africa. METHODS: Document review was used to identify appropriate disease determinants to decrease risk in children < 5 years old in the study area. These were used to develop lyrics and music for a song about malaria in line with the principles of participatory risk analysis. The age and cultural appropriateness of the song as well as disease determinants chosen were reviewed using a modified Delphi technique, by 10 purposively selected experts in malaria (4), Vhavenda music (3) and early childhood education (3). Thereafter, the song was translated into Tshivenda and reviewed by two focus groups living in the study area, one including female caregivers and pre-school teachers (n = 7) and a second comprising of male community based malaria control personnel (n = 5). RESULTS: The experts surveyed and both focus groups strongly supported the inclusion of knowledge about the link between mosquitoes and malaria and that children should know the signs of malaria to facilitate early diagnosis. Although the expert group felt that bed nets should not be mentioned, both focus groups suggested the inclusion of bed nets and it was observed that community members were purchasing their own nets. Focus group members also felt that young children should not be involved in internal residual spraying initiatives. CONCLUSIONS: It was concluded that although risk communication on malaria prevention and treatment in young children should be aimed at caregivers, an age and culture appropriate song about malaria could be developed to help young children protect themselves. This song focused on understanding the link between mosquitoes and malaria, preventing exposure and recognising signs of disease.

Mrs. Robinson's Revenge: Pete Seeger, Earl Robinson, and the Medicare Protest Song.

In 1962, Pete Seeger recorded "The Ballad of Doctor Dearjohn" about Canadian Medicare and the Saskatchewan doctors' strike of the same year. How had this New Yorker, recently relieved of a jail sentence, learned of Medicare in the distant prairie province? And why was his song never released? This paper traces the ballad's fortunes through the papers of composer Earl Robinson (University of Washington) and the archives of the American Medical Association. It is situated in the historiography of folk revival and the expatriate adventures of artistic Americans persecuted in the McCarthy era.

En 1962, Pete Seeger a enregistré « La ballade du docteur Dearjohn ¼ à propos de l'assurance-maladie canadienne et de la grève des médecins en Saskatchewan la même année. Comment ce New-Yorkais, récemment libéré de prison, a-t-il eu connaissance des événements survenant dans une province éloignée ? Et pourquoi sa chanson n'a-t-elle jamais été commercialisée ? Cet article retrace le parcours de la ballade à travers les archives du compositeur Earl Robinson (Université de Washington) et les archives de l'American Medical Association (Chicago). Il se situe dans l'historiographie du renouveau folk et des aventures d'artistes américains expatriés suite aux persécutions vécues à l'époque du maccarthysme.

Younger African American Adults' Use of Religious Songs to Manage Stressful Life Events.

The aim of this study was to explore the use of religious songs in response to stressful life events among young African American adults. Fifty-five young African American adults aged 18-49 participated in a qualitative study involving criterion sampling and open-ended interviews. Data analysis included content analysis and descriptive statistics. Stressful life events were related to work or school; caregiving and death of a family member; and relationships. Religious songs represented five categories: Instructive, Communication with God, Thanksgiving and Praise, Memory of Forefathers, and Life after Death. The tradition of using religious songs in response to stressful life events continues among these young adults. Incorporating religious songs into health-promoting interventions might enhance their cultural relevance to this population.

Neural correlates of binding lyrics and melodies for the encoding of new songs.

Songs naturally bind lyrics and melody into a unified representation. Using a subsequent memory paradigm, we examined the neural processes associated with binding lyrics and melodies during song encoding. Participants were presented with songs in two conditions: a unified condition (melodies sung with lyrics), and a separate condition (melodies sung with the syllable "la"). In both cases, written lyrics were displayed and participants were instructed to memorize them by repeating them covertly or by generating mental images of the songs. We expected the unified condition to recruit the posterior superior temporal gyrus, known to be involved in perceptual integration of songs, as well as the left inferior frontal gyrus (IFG). Conversely, we hypothesized that the separate condition would engage a larger network including the hippocampus to bind lyrics and melodies of songs, and the basal ganglia and the cerebellum to ensure the correct sequence coupling of verbal and musical information in time. Binding lyrics and melodies in the unified condition revealed activation of the left IFG, bilateral middle temporal gyrus (MTG), and left motor cortex, suggesting a strong linguistic processing for this condition. Binding in the separate compared to the unified condition revealed greater activity in the right hippocampus as well as other areas including the left caudate, left cerebellum, and right IFG. This study provides novel evidence for the role of the right hippocampus in binding lyrics and melodies in songs. Results are discussed in light of studies of binding in the visual domain and highlight the role of regions involved in timing and synchronization such as the basal ganglia and the cerebellum.

Divergence in mating signals correlates with genetic distance and behavioural responses to playback.

Animals use acoustic signals to defend resources against rivals and attract breeding partners. As with many biological traits, acoustic signals may reflect ancestry; closely related species often produce more similar signals than do distantly related species. Whether this similarity in acoustic signals is biologically relevant to animals is poorly understood. We conducted a playback experiment to measure the physical and vocal responses of male songbirds to the songs of both conspecific and allopatric-congeneric animals that varied in their acoustic and genetic similarity. Our subjects were territorial males of four species of neotropical Troglodytes wrens: Brown-throated Wrens (Troglodytes brunneicollis), Cozumel Wrens (T. beani), Clarion Wrens (T. tanneri) and Socorro Wrens (T. sissonii). Our results indicate that birds respond to playback of both conspecific and allopatric-congeneric animals; that acoustic differences increase with genetic distance; and that genetic divergence predicts the strength of behavioural responses to playback, after removing the effects of acoustic similarity between subjects' songs and playback stimuli. Collectively, these results demonstrate that the most distantly related species have the most divergent songs; that male wrens perceive divergence in fine structural characteristics of songs; and that perceptual differences between species reflect evolutionary history. This study offers novel insight into the importance of acoustic divergence of learned signals and receiver responses in species recognition.

The organisation of musical semantic memory: evidence from false memories for familiar songs.

By adapting a well-known paradigm for studying memory for words-the Deese-Roediger-McDermott or DRM paradigm (Deese, 1959, Roediger & McDermott, 1995)-the two experiments reported here explore memory for song titles and song clips. Participants were presented with five song titles (Experiment 1a) or five 30-second song clips (Experiment 1b) for each of nine popular artists (e.g., Robbie Williams). The most popular song identified for each artist in a pilot task was omitted from the sets of titles/clips. Following a distractor task, participants were asked to write down as many of the songs as they could recall. They were also asked to return a week later and complete a second recall task. Participants falsely recalled a significant number of the related but non-presented songs in both experiments and this increased a week later, while correct recall for presented items decreased. The results are discussed in terms of theory for musical memory as well as in the context of providing a novel method for exploring the organisation of musical memory.

The role of singing familiar songs in encouraging conversation among people with middle to late stage Alzheimer's disease.

BACKGROUND: Language deficits in people with Alzheimer's disease (AD) manifest, among other things, in a gradual deterioration of spontaneous speech. People with AD tend to speak less as the disease progresses and their speech becomes confused. However, the ability to sing old tunes sometimes remains intact throughout the disease. OBJECTIVE: The purpose of this study was to explore the role of singing familiar songs in encouraging conversation among people with middle to late stage AD. METHODS: Six participants attended group music therapy sessions over a one-month period. Using content analysis, we qualitatively examined transcriptions of verbal and sung content during 8 group sessions for the purpose of understanding the relationship between specific songs and conversations that occurred during and following group singing. RESULTS: Content analysis revealed that songs from the participants' past-elicited memories, especially songs related to their social and national identity. Analyses also indicated that conversation related to the singing was extensive and the act of group singing encouraged spontaneous responses. After singing, group members expressed positive feelings, a sense of accomplishment, and belonging. CONCLUSIONS: Carefully selecting music from the participants' past can encourage conversation. Considering the failure in spontaneous speech in people with middle to late stage AD, it is important to emphasize that group members' responses to each other occurred spontaneously without the researcher's encouragement.

Objective and Subjective Assessment of Music Perception and Musical Experiences in Young Cochlear Implant Users.

For many individuals, music has a significant impact on the quality and enjoyability of life. Cochlear implant (CI) users must cope with the constraints that the CI imposes on music perception. Here, we assessed the musical experiences of young CI users and age-matched controls with normal hearing (NH). CI users and NH peers were divided into subgroups according to age: children and adolescents. Participants were tested on their ability to recognize vocal and instrumental music and instruments. A music questionnaire for pediatric populations (MuQPP) was also used. CI users and NH peers identified a similar percentage of vocal music. CI users were significantly worse at recognizing instruments (p < 0.05) and instrumental music (p < 0.05). CI users scored similarly to NH peers on the MuQPP, except for the musical frequency domain, where CI users in the children subgroup scored higher than their NH peers (p = 0.009). For CI users in the children subgroup, the identification of instrumental music was positively correlated with music importance (p = 0.029). Young CI users have significant deficits in some aspects of music perception (instrumental music and instrument identification) but have similar scores to NH peers in terms of interest in music, frequency of music exposure, and importance of music.

A new species of Svistella Gorochov, 1987 from Xizang, China (Orthoptera, Trigonidiidae, Trigonidiinae).

The genus Svistella Gorochov, 1987 includes 10 species from Asia, with nine documented in China. In this study, a new species, Svistellayayun He, sp. nov., is described from Xizang, China. Morphologically, it resembles S.rufonotata (Chopard, 1932) but can be distinguished by a smaller inner tympanum, dark-brown setae on the 5th segment of the maxillary palp, and a rounded apex on the ectoparamere. To validate our morphological inferences and support the description of S.yayunsp. nov. as a new species, we performed a PCA based on bioacoustics parameters and molecular analysis. All Svistella species documented in China are distinguished by integrating their songs and DNA barcoding.

Lithuanian polyphonic songs sutartines: the archaic nature of their musical language in the context of global music.

Lithuanian traditional polyphonic songs, known as sutartines, are characterized by a distinctive musical language and have almost no analogues in world music. The aim of this article is to explore the peculiarities of their musical language and the socio-cultural context of their performance tradition in order to reveal their archaic origins. The archaic nature of sutartines songs is shown not by individual features of their musical language, but by the totality of these features, the peculiarities of their poetics, and performance traditions. An examination of the musical elements and poetry of these songs, and their juxtaposition against examples of archaic vocal polyphony from other cultures, leads to the convergence of arguments in favour of the very ancient origins of these songs, possibly dating back to Old Europe (c. 3 millennium BC). A deeper insight into sutartines songs significantly enriches our understanding of the origin and development of traditional vocal polyphony.

"Fill the World with Love": Songs with Prosocial Lyrics Enhance Online Charitable Donations among Chinese Adults.

Research has shown that songs with prosocial lyrics can enhance individual prosociality. Building on the general learning model (GLM), this study demonstrated, through real-world charitable organizations, how songs with prosocial lyrics influence helping behavior that uses time as a currency. In Study 1, participants were randomly assigned to conditions of prosocial songs, prosocial lyrics, or neutral songs, and they were instructed to complete an online charity task. The results indicated that compared to the neutral songs, participants listening to prosocial songs and lyrics spent more time donating rice to the United Nations World Food Programme. This effect was replicated in Study 2, employing different media exposure from Study 1 (i.e., listening to background music). Furthermore, investigations into the underlying mechanisms revealed that this effect was mediated by interpersonal empathy. In summary, current findings suggest that songs with prosocial lyrics increase interpersonal empathy, subsequently influencing people's online charitable donation behaviors in daily life.
